Our resent invention relates generally to water lifting devices and more particularly to water lifting devices of the t pe described and claimed in Patent Num er 1,100,491 granted to Lucius G. Rose under date of June 16, 1914, our primary object beingthe improvement and refinement of such apparatus'so as to adapt the same to a wider range of^usefulness including substantially deeper operations.

According t9 our invention, we pl'pose to eliminate the shaft supporting frame of the above patent and support the shaft by an up- Iright tube in connection with which the vshaft is so mounted as to permit of adjustment of the impeller in its casing from the upper end of the shaft as well as to create several bearings whose presence avoids whippin of the shaft, and provide for thefconstant ubrica- .20 tion of these bearings.

In the accompanying drawing, which illustrates our present iiivention and forms a l ,I part of this specification,

Figure l, is a perspective view of our iin- 25 proved water lifting device,

Figures 5 and 6 are detail longitudinal sectional views taken throu h certain ortions of the shaft housing an showing a ternate internal bearing arrangements.

Referring now to this drawing, our improved water liftin device comprises a rotary bladed impe er mounted rigidly upon the lower end of a shaft 11 within a two partcasin 12\whose upper and lower arts arewbol togetherand have centrally ocated upper and lower inlet openings 13, the vformer being around the'lower portion of the shaft 11. ,The casing 12 also has a side outlet 14 and to this outlet a suitable dischar e pipe 15 of flexible or rigid nature is coup ed use. The impeller casing 12 is, inuse, submerged-within the water to be` lifted and is preferably mounted u on skids 16 soas to elevate substantially a ove the boso'm of the body of water in which it is h l l Above the casing 12, and secured at the outer ends of'its radial arms 17 upon bosses 18 of said casing, is a spider frame 19 having a centrally upstanding tubular portion 20 .the oil being held against and a lower counter-bored boss 21 alined with tube 20. The shaft 10 upstandsv i through the boss 21 and tube 20 and also through a tubular casing 22, the lower end of the latter of which isconnected by a threaded coupling 23. In the counter-bore ofbelow the upper end of shaft 11, is closed by a tubular ad]usting nut 26 threaded therein and which surrounds the shaft and has an upper flan d head 27 formin a support for a thrust arin 28 preferab y of antifriction type. To 51e upper portion of the casing '22 the lower en of a U-shaped bracket 29 is securel clamped and the upper. end of this brac et carries an anti-friotion bearing' 30 for the upper end of the shaft 11 at a oint substantially above the upper end of t casing 22. 5

Above the bearing 28, a anged collar 31 is secured to the shaft 11 the flange of this collar resting on the said bearing so as to thus support the weight and downward thrust of the shaft 11 and impellerfO and permit of adjustment of the latter so as to clear and center the same vertically in the' 'nsl casing 11 by adjusting the nut26 at the upper end of the casing 22. A belt-driven wheel 32 is ke ed or otherwise fixedto shaft 11 above the anged collar 31 and upon that portion of the ,shaft which isbraced an strengthened by the bracket 29. 'r

The length of the casing 22 is of course dependent upon the length of the shaft desired for anyparticular use, but where these parts are employed of a length'likely to permit whipping of the shaft in the casing, we propose internal 'bearings' of any suitable character such for instance as shown in

Fi ures

5 and 6. In Figure 5 a bearing33 1s shown around the shaft within the casing, having an annular rib portion engaged between the ends of adjacentl casing sections connected by Figure 6 the tubular bearing 35 interfits the casing 22 around the shaft andv is held in place b a set screw 36 through the casing. t is o vious, however, that other internal will be lubricated thoroughl y since, in use; the casing 22 forms therein an oil reservoir,

of the lower packing 24 which also acts to a. threaded coupling 34. In
